The Marlins’ farm system is closing out the season with a little bit of everything: postseason games for two affiliates, breakout performances from 2025 Draft picks, major-league contributions from a pair of Top 100 prospects and injury setbacks that slowed three more.
Single-A Jupiter opened a best-of-three postseason series against Daytona on Tuesday, and Double-A Pensacola was set to face Biloxi on Tuesday as well. That gives Miami two clubs still playing meaningful baseball while the rest of the system wraps up another busy year.
At the big-league level, Owen Caissie and Joe Mack both made an impact, while Thomas White, Robby Snelling and Kevin Defrank each missed significant time because of injuries. Meanwhile, Cam Cannarella and Brandon Compton, both taken in the 2025 Draft, surged across three levels.
Marlins director of player development Rachel Balkovec recently spoke with MLB.com about where the organization sees its 2026 farm system heading, and she pointed to several areas where the group believes real progress has been made.
The biggest jump, she said, showed up in the power numbers.
“Last year was kind of our first year, if you will, of implementing our new hitting system, and last year was a lot about plate discipline, and this phase was a lot more about bat speed. We really leaned into strength and conditioning, and really, really pushed hard on that. So, I'd like to think it's a combo of our hitting department and our strength and conditioning department working together on that.”
Balkovec also highlighted improvements on the bases, where the system has added more value in more than one way.
“We've done some pretty cool stuff on the baserunning, basestealing side. Last year probably broke out on the basestealing side, but this year baserunning as well.
Just seeing us get to the top of some of those categories like [going] first to third. Our routes are better.
Just tightening baserunning has been really good.
“Our infield and outfield defense is top across top to bottom. We've made a lot of strides in player development, and also, obviously, it doesn't hurt to trade for great players.
Everything our acquisition teams have done, from amateur to international to everything. It's been a true team effort across the board to really improve the system.”
She also addressed the development path for one of the younger players in the mix, saying, “He's got things to work on and develop, just like everyone else. We would have hoped.
He would have hoped, of course. He's still young.”
And on Defrank, Balkovec offered a more encouraging update: “Tough one for Defrank, but he's trending positively, and there's no reason to believe that he wouldn't be ready to go next year.”

Sandy Alcantara Just Made Miamis 2027 Outlook A Lot More Complicated
Sandy Alcantaras season has been one of the more important developments in Miami, even before you get to the broader implications for the clubs future. After working his way back from Tommy John surgery and a difficult 2025, the right-hander has given the Marlins something they badly needed: stability in the rotation and a reminder of what a healthy Alcantara can still mean. His summer stretch backed that up, with strong July and August numbers helping define a rebound that looked far more encouraging than what Miami got a year ago.
Even with a rough recent start in which he gave up seven runs in 4.1 innings, Alcantara has still kept piling up value by taking the ball every fifth day and getting deep into the season. That matters for a Marlins team trying to map out what comes next, because a pitcher who looks reestablished can change the conversation around the rotation, the offseason, and the timeline for 2027. The bigger question now is how much Miami can count on this version of Alcantara as it builds forward. [Read more 🡒]
